How do i find the circumference of a circle when the given radius is 3 1\2 cm, answers in terms of π ​

Circumference of circle is 97.42cm.

Step-by-step explanation:

Here we have given that A circle with having radius 31 / 2 cm. And We need to find circumference of circle.

Formula using

Circumference of circle = π × 2 × radius

substitute the value

Circumference of circle = π × 2 × 31 / 2 cm

cancle the 2

Circumference of circle = π × 31 cm

Using π = 22 / 7

Hence, Circumference of circle is 97.42cm.

i would say the third one.

step-by-step explanation: liner would mean in a line and the only one that doesn't look like it's even thinking about forming a line would be the third one

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
